TWDB Freshwater Flows Project- July 12, 2021

In late June, RATES completed installation of the first two of four RTHS stations for the TWDB-funded Freshwater Flows project, both in Willacy County.  Station TWDB-1 is monitoring the Raymondville Drain, and station TWDB-2 is monitoring the Hidalgo-Willacy Main Drain.  On July 6-7, the region received significant rainfall; airports in MacAllen, Harlingen, and Brownsville, respectively recorded 2.11, 4.63, and 5.07 inches of precipitation over the two days.  The resulting surge in stage height was recorded by the water level sensor systems at both stations.
